.38 vs .357 bullet drop

38 vs .357 bullet drop
Would there be a significant difference in .38 vs .357 bullet drop at 25, 50 and 75 yards?

For purposes of sighting in a .357 for deer using .38.
Cost is a factor and I have no .357 but I do have 2 boxes of .38.
Plan is to practice with the .38 and then get a box of .357 to hunt with and shoot 15 of the box of 20 .357 loads as a final practice.
Assuming I'm accurate enough to use in a hunt.

So would the two loads hit pretty much at the same point at the same distance of 25, 50, and 75 yds?

Assume WWB .38 and .....?? 180gr buffalo bore .357

Yes, maybe. And, it's not drop at the closer ranges, but difference in point of impact because of differences in recoil of the gun. I've had guns that shot pretty close, I've had 'em that even had windage differences, never quite figured that one out, but my old Security Six shot way left with .38s if sighted for magnums in addition to the elevation difference.

At 75, .38 will be dropping like a rock. Don't even figure to hit close to a .357 round, much flatter shooting beyond 50, even if sighted in for the load in question at 25 or 50. My Blackhawk shoots a 180 XTP at 1400 fps or a little over. Sighted dead on at 100, it's 5" high at 50. That difference and some grass in the way and my stupidity for not thinkin' about it in the excitement (mostly the problem :banghead caused me to miss a hog at about 50 yards a few years ago. I'm still reliving that shot, knew I'd screwed up the minute the hammer fell. My 158 grain .357 shoots dead on at 50 and about 8" low at 100 with that sight in and had I been using it, I'd have gotten that hog. Or, if I'd had my head somewhere where the sun was shining before squeezing the trigger...:banghead: The whole idea of the sight in was that I'd take a 6 O'Clock hold at 50 and combat hold at 100, but hell, one forgets when the danged hog presents itself. DUH But, I didn't really want a third mark on my sight as I use the 158 a lot for practice, probably another screw up as when the chips are down and you ain't thinkin', you tend to revert to practice/training.

On my Taurus 66 and my Blackhawks I have elevation marks scratched into the sight for proper set for .38 or .357 loads. I can make the change instantly in the field. This is why I like my trail guns to have adjustable sights and why guns like the 3" SP101 don't thrill me for this sort of use when I can get a M60 Smith or a medium frame gun like my Taurus that totes just as easy on a belt, but has adjustable sights. I suspect this is the whole reason for the adjustable sighted Smith M60s, one even having a 5 inch barrel. Those are pretty cool trail guns, light and easy to carry, but very accurate and useful with a variety of loads for small game to deer/hog in a survival situation or just for sport.

Sight in with the same ammo you intend to hunt with, PERIOD!

If you want to practice with other, sobeit, just don't expect it to shoot to the same POI.
